Résumé :

RESUMO - No presente estudo pretende-se contribuir sobre a compreensão geológica da porção onshore Bacia Sedimentar do Espírito Santo, onde há poucos estudos publicados. Identificaram-se fácies sedimentares de maior ocorrência como fácies rudáceas, areníticas e lamíticas, com cores branca a cinza claro, formando depósitos tabulares com gradação normal e interacamadados. Estratificações acanaladas incipientes foram observadas, assim como feições de acresção lateral, escavação e preenchimento de canais. As fácies areníticas e rudáceas são mal selecionadas, matriz-suportadas, constituídas princip

Résumé :

Based on the observation and description of single well and outcrops and the analysis of reservoir compositions, petrology, clastic structure and sedimentary structure,this paper determines the sedimentaty facies characteristics of Tanzhuang formation. The types of sedimentary facies in late Triassic epoch are delta front,shallow lake and semi-deep lake. The delta front develops subaqueous distributary channel, mouth bar and distal bar. Lacustrine facies develops shallow lake mud, shallow lake sand bar, turbidite sand and semi-deep lake mud.The reservoir rock formations in this area are lithic

Résumé :

Os arenitos de praia, ou beachrocks, são sedimentos que sofreram um processo de litificação e são encontrados paralelamente à linha de costa na zona intermaré, apresentando uma forma alongada, estreita e cimentados por carbonato de cálcio. O processo de diagênese consiste na formação da rocha sedimentar propriamente dita a partir da compactação, dissolução, cimentação e recristalização. O estudo da formação e diagênese do arenito de praia são relevantes pois possibilita o entendimento de como as rochas sedimentares detríticas são geradas, além de reconhecer como a variação do nível do mar se c

Résumé :

Igneous intrusions in sedimentary basins are commonly related with mineralogical association changes in host-rock. At Sapopema region (Paraná State, southern Brazil), an extensive diabase sill (associated to Serra Geral Formation) was emplaced in pelitic-carbonate succession during post-Triassic. The sedimentary host-rock association includes mostly shale, siltstone and carbonate of the Permian Irati Formation.

AbstractThe great historian V. O. Kliuchevskii found the key to Russian society in the relative simplicity of its social forms in comparison with Western Europe. But in writing his magisterial Course in Russian History he revealed a degree of complexity that belied his disarming formula. The apparent contradiction stems from the standard of comparison. There were elements of complexity in Russian society that had no counterparts in the experience of the West. Moreover, the definition of society in nineteenth-century social history may have been too confining. If we make the effort to explore t

Field investigations in 2013–2014 on acid soils and in 2016–2017 on sedimentary soils showed that populations of two lymnaeids had decreased in number in central France since 1998.

Résumé :

The lithologic melange accumulation of areskum formation in akshabluk area is one of the key strata in exploration. Its basement inheritance controls the whole process of Jurassic sedimentation, and the filling and leveling gradually reduces the terrain elevation difference; After the late Jurassic deformation, the flat paleogeomorphology was changed and the deposition of Early Cretaceous strata was controlled. Under the control of marker beds, sedimentary cycles are divided according to the cycle characteristics of logging curves. Under the control of cycle interface (standard layer), accordi

Résumé :

Abstract In-depth analysis of the characteristics of water and sedimentary changes at the confluence of the upper reaches of Weigan River and Heizi River is the prerequisite and basis for studying the future water and sedimentary situation in the Kizil Reservoir. This article analyzes the trend, mutation point and periodicity of the water and sedimentary sequence with multi-methods. The double cumulative curve method and the attenuation analysis method were used to analyze the impact of precipitation and human activities on runoff and sedimentary transport, and other influencing factors were q

Résumé :

Since the 1950s, mixed sedimentation has come into people's attention, and has gradually become the research direction of sedimentology. On the basis of previous studies, the research progress of mixed deposition at home and abroad is summarized, and some problems and prospects of mixed deposition are put forward. Mixed sediment is widely developed in Marine and lake sedimentary environments. As a special sediment with complex sedimentary patterns, it is controlled by many factors such as terrigenous supply, climate change, sea level change, hydrodynamic conditions, tectonic action and so on.

Résumé :

The sedimentary facies is the combination of the sediment which has some rules of lithological and construction characters and paleontological evidence. It characterizes the source direction and the strength degree of water dynamics. As the developmental situation of the reservoir of different sedimentary facies is different, the permeability, porosity and oil saturation is distinctive. The production is related to the sedimentary facies, this lead to the different production capacity of different sedimentary facies. The oil-producing capacity varies with the sedimentary facies of the reservoi
